Happened when trying to switch to Apps menu from Most visited menu on blank page.

Status changed to 'Confirmed' because the bug affects multiple users.

Closing now as this report wasn’t investigated timely and is now too old to be meaningful.
Please do not hesitate to report crashes occurring with recent releases of chromium-browser, they will hopefully be investigated and acted upon in a more timely manner.
